BULK DENSITY Bulk density is a material's weight per unit volume (i.e. lbs,/ft³, gms/cc) and can be obtained in loose, (fluidized) packed or dynamic conditions. When large weight differences exist between the packed and loose bulk density, this may indicate that the material may be easily fluidized or is pressure-sensitive.

What Is the Bulk Density of Coal? - Reference.com

Apr 04, 2020· The three types of coal are anthracite coal, bituminous coal and lignite coal. Anthracite coal has a bulk density of 50 to 58 pounds per cubic feet, or 800 to 929 kilograms per cubic meter. It is a mature coal and is very hard and shiny. Bituminous coal has a bulk density of 42 to 57 pounds per cubic feet, or 673 to 913 kilograms per cubic meter.

Fly ash - Wikipedia

Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash.
